newfound myspace obsession

so i've been a member of myspace for quite some time now. i never really cared about it that much because facebook was already consuming my life. besides, i've never been a real internet kind of person, except when i didn't have my license and lived on yahoo messenger. but anyway, i set up a myspace profile awhile ago just because i felt it was the thing to do since "everyone" was on myspace. but one night about a week ago i honestly spent around 5 hours non-stop on myspace editing my profile, searching for people from high school, uploading pictures, trying to find the perfect profile song, etc. when you're on that thing for awhile it is so hard to stop. i thought it was kind of funny though that hardly any of my high school friends that have facebook had a myspace account yet a bunch of my friends from high school who never went to college were all about their myspace profiles. in my opinion, myspace is different from facebook in the way that you can lie so easily about anything. i'm not talking about the whole pedophile thing, but just about creating completely different identities. i found out things about peoples' personalities that i really did not know before. like one of my semi friends who dresses pretty preppie and seems fairly normal comes across as this huge death-is-so-cool-and-i-love-fire emo chick on her profile. so if people are putting this on their profiles yet acting completely different in person, do you really KNOW anyone?
